Abstract
An image processing apparatus includes an acquisition unit to acquire an image. A detection unit detects each object region from the image acquired by the acquisition unit. A luminance distribution calculation unit calculate a plurality of luminance distribution information for respective object regions detected by the detection unit. A representative luminance value calculation unit calculates a plurality of representative luminance values for respective detected object regions. A determination unit determines tone characteristics for respective object regions based on the plurality of luminance distribution information for respective object regions calculated by the luminance distribution calculation unit and a relationship among the representative luminance values for the respective object regions calculated by the representative luminance value calculation unit.
